Claims

[Claims for Utility Model Registration] A cutting blade is constituted by a ridge line where an upper surface and one side intersect, and the cutting blade is removably attached to the outer circumference of a tool body that is rotated about an axis, and the cutting blade is The tool body is attached in such a manner that it is inclined so that it advances in the direction of rotation of the tool body as it approaches the tip side of the tool body,
In a throw-away chip in which the upper surface and one side surface are used as a rake surface and a flank surface, respectively, the rake angle of the cutting edge is approximately equal at any location in the axial direction of the tool body. The portion that intersects with one side surface is inclined in the direction opposite to the rotation direction at a larger angle toward the proximal end of the tool body, while the clearance angle of the cutting edge is approximately equal at any location in the axial direction. The throw-away tip is characterized in that the one side surface is inclined at a larger angle toward the proximal end of the tool body, corresponding to the slope of the upper surface.
